Definitions

  • the present invention relates to increasing the efficiency and dust pick-up and collecting performance of the brush used in vacuum cleaners.
  • Vacuum cleaners are machines with very low efficiency values.
  • the power of the motor used in the vacuum cleaners is 1400 W. However only 300 W of this power is used for an efficient dust suction. Furthermore this power value of 300 W is consumed only for the suction of micron sized dust particles. For this reason, there is a need of a vacuum cleaner with a much higher efficiency, having a maximum dust pick up capacity at a lower power value.
  • a suction inlet is arranged in the middle or near to the front of the base of the brush used in the vacuum cleaners.
  • the dirt or dust is picked up from the ground depending on the suction capacity of the vacuum cleaner, it is directed towards the said suction inlet by means of the channels located at the bottom surface of the brush.
  • Channels are provided along the bottom of the brush, in order to provide a uniform pressure distribution along its bottom surface as well as to provide a homogeneous suction.
  • these channels are arranged symmetrically on the right and left sides of the brush.
  • the pressure distribution created at the base of the brush is an important parameter influencing the dust pick up and suction.
  • dust is sucked-in from a single point.
  • the suction inlet port is located at the centre of the brush, the zone where maximum dust suction is realized is the middle part of the brush; therefore high pressure values are created at the bottom of the brush and a homogeneous suction cannot be provided along the width of the said brush.
  • the use of the brush is causes difficulties for the user by increasing the force applied at the direction opposite to that applied by the user.
  • the object of the present invention is to increase the efficiency and dust pick up performance of the brush used in the vacuum cleaners.
  • Figure 1 is the view of the prior art vacuum cleaner brush, shown from the bottom.
  • Figure 2 is the cross-sectional view of the vacuum cleaner brush taken from the line A-A.
  • Figure 3 in the bottom view of the vacuum cleaner brush.
  • Figure 4 is the perspective view of the guide.
  • the flow of the debris sucked in together with air is guided towards the suction inlet port (4) of the vacuum cleaner by means of a guide (2) placed inside the brush (1).
  • the guide (2) consists of symmetrical concave lateral edges (6) and a suction inlet port window (5) with an opening which matches with the suction inlet port (4).
  • the guide (2) is so placed along the brush (1) that its opening is at the base of the brush.
  • the suction inlet port window (5) provided at the upper portion of the guide (2) overlaps with the suction inlet port (4) and it has a width that matches with the suction inlet port (4).
  • the lateral edges (6) of the guide (2) may also be bent in a convex form as well as in a concave form. It can also consist of straight lateral edges (6) with a certain slope.
  • a turbulence is created inside the guide (2) placed within the brush (1), when the flow reaches to extremely high speeds.
  • a profile (3) is used in order to enhance the performance while directing the debris received in together with air towards the suction inlet port (4).
  • An elliptical profile (3) to direct the flow coming from the front and back of the brush separately towards the suction inlet port (4) with a minimum loss, is placed along the guide in such a manner that it is centrally located in the guide (2).
  • the length of the profile (3) is shorter than that of the guide (2) and the profile (3) is mounted in the recesses (12) provided on both sides of the guide (2) so that no gap is left between the profile (3) and the guide
  • a catch (10) is provided at the point of the profile which matches with the suction inlet port window (5), in order to facilitate the guiding of the debris laden air towards the suction inlet port (4) and to regulate the air flow at the suction inlet port (4) of the brush (1); the surface of which, facing the suction inlet port (4) is straight, whereas the other surface has a certain inclination.
  • the said profile (3) may be elliptical or can be circular or equilateral rectangular.

Abstract

Selon l'invention, l'écoulement des débris aspirés en même temps que l'air est guidé vers l'orifice d'entrée d'aspiration (4) de l'aspirateur, au moyen d'un élément guide (2) placé à l'intérieur de la brosse (1). Cet élément guide (2) comporte des bords latéraux concaves symétriques (6) ainsi qu'une ouverture d'entrée d'aspiration (5) correspondant à l'orifice d'entrée (4). Lorsque les bords latéraux (6) de l'élément guide (2) sont inclinés selon un certain degré, les pertes qui peuvent se produire au niveau de la zone d'écoulement sont minimisées. L'élément guide (2) est placé le long de la brosse (1) de manière que son ouverture se situe à la base de la brosse. L'ouverture d'entrée d'aspiration (5), ménagée au niveau de la portion supérieure de l'élément guide (2), chevauche l'orifice d'entrée d'aspiration (4) et elle possède une largeur qui correspond à celle de cet orifice (4). En outre, les pertes de pression sont évitées, du fait que l'on empêche l'air chargé de poussières de pénétrer dans des régions non voulues de la brosse (1), et ce grâce à l'élément guide (2).
